  1. Coefficients and 95% confidence intervals are presented. P values obtained with Tukey method adjusted for multiple comparisons. ‘Group’ and ‘day’ are fitted as random effects; we show the variance associated with them. The mealworms eaten by first crossers were excluded by the analysis in order to maintain data independence. Results are in the log (not in the response) scale.
